How do you know there isn't a russian doll scenario of sock puppets all the way down, and some other hedge fund isn't going to profit in a few months from all of this on a trade we never heard about? After all, the hedge fund industry as a whole does better, not worse, when there is lots of churn, even when that churn means places with names like Melvin every now and then go under. I admit this scenario is not likely, but still, the should statements can be misleading, and I don't recommend them.
